PATENT OFFICE.

OF LAPEL, INDIANA.

LAWN-COASTER.

SPECIFICATION forming part of Letters Patent N o. 664,920, dated January 1, 1901.

Application filed July 2, 1900.

To @ZZ whom, it may concern.

Be it known that I, GEORGE W. WRIGHT, av citizen of the United States, residing at Lapel, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Lawn-Ooasters, of which the following is a specification.

rIhis device is designed as a substitute for the ordin ary double swing,which is much used for purposes of rest and recreation; and, generally speaking, itconsists of a frame mounted on rollers, so as to be easily reciprocated back and forth, carrying the occupants in a horizontal instead of a curvilinear direction, thus differing from the swings above referred to. This forms, in effect,a riding-chair, which, as it is commonly used out of doors, I have denominated a lawn-coaster, although it may be used indoors also, and when constructed of suitable size and style is appropriate for sitting-rooms and parlors.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, Figure lis a perspective view of a double chair or coaster embodying my said invention; Fig. 2, an end elevation of the same on an enlarged scale; Fig. 3, a detail sectional view, as seen from the dotted line 3 3 in Fig. l, on a still further enlarged scale; and Fig. 4 is a fragmentary horizontal sectional view as seen when looking downwardly from the dotted line a et in Fig. l. Y

In detail this apparatus has a base l, constructed in any suitable manner, preferably from timbers and boards, and which is designed to be stationary. `Its top constitutes the floor upon which the feet of the occupants rest when the device is in use. Secured to this base l are four roller-housings 2, which contain the rollers or trucks 3, upon which the movable frame rests. These housings, as best shown in Fig. 3, are bifurcated, the two sides being that distance apart which is capable of receiving the rails of Jthe movable frame. They are also horizontally slotted and receive the gudgeons of the antifriction trucks or rollers 3,while the peripheries of said rollers come in contact with the rails of the movable frame above referred to. These Serial No. 22,349. (No model.)

erwise secured together, the bars 4 and. 5 respectively passing above and below the trucks or rollers 3, as shown. Connected to the crossbars 7 of the reciprocating frame and to the iioor of the base l are torsional springs 9, which aid in returning the reciprocating frame to a central position after it has been pushed endwise by the occupant. These springs I have found in practice to add considerably to the desirability of the apparatus.

The seats are formed by securing to crossbars 10 and ll of the reciprocating frame a suitable piece of fabric l2, which, as shown in Fig. l, makes a comfortable and desirable seat.

In use the one or two occupants after seating themselves in this apparatus push gently with their feet upon the base 1, which drives the reciprocating frame back and forth, the motion being aided, as above stated, by the springs 9.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a base, roller-housabove and below the rollers, whereby said frame is securely held from accidental disengagement, substantially as shown and described.

3. The combination, of a base, a movable l frame mounted thereon, seats for occupants IOO in seid movable frame, and torsional springs hand and seal, at Lapel, Indiana., this 30th connected to cross-bars on the ends of the day of June, A. D. 1900. 4 frame at one end and extending in and conw nected to said base at the other end and thus l GEORGE W' WRIGHT' [L S'] v5 adapted to aid in the reciprocal movement of Witnesses:

the movable frame, substantially as set forth. ED S. HUTTON,

In Witness whereof I have hereunto set my 1 ROBERT C. WRIGHT.
